Here are two different groups shot by me and my BIL for his first time ever shooting at 500yds. He shot the 3rd group on the right with my 16" Grendel, and I shot the left 2rds before moving further. Wind conditions varied from 11-17mph at full value from left to right, from my best recollection. He was shooting with my wind calls. The other marks are from 5.56 that I didn't witness.

This was after my BIL flattened some 12" poppers at 300yds with the 90gr TNT.
